Abstract
Numerical methods for solving simple macroscopic traffic flow continuum
models have been studied and efficiently implemented in traffic
simulation codes. The Lax method is an explicit method which
has been implemented to solve simple continuum model in the traffic
simulation package KRONOS. In this part of the project we studied
the implementation of the Lax method for solving a high-order flow
conservation traffic model on Parallel Computers. We wrote an experimental
code in C to simulate a freeway traffic flow. Tests with
real data collected from the 1-35 W freeway in Minneapolis were conducted
on a workstation computer. We then implemented the high
order Lax method on a parallel machine and run tests with real data
collected from an 18-mile stretch of the 1-494 freeway. The parallel
implementation demonstrated significant execution time speedup.
